Manner of chaps going round Italy (4)
I believe the answer is:
mien
'manner' is the definition.
(mien is a kind of manner)
'chaps going round italy' is the wordplay.
'chaps' becomes 'men' (I've seen this before).
'going round' means one lot of letters goes inside another.
'italy' becomes 'i'.
'men' placed around 'i' is 'MIEN'.
'of' is the link.
(Other definitions for mien that I've seen before include "A person's demeanour" , "Counterance - mine?" , "The carriage" , "A countenance like mine" , "Person's bearing" .)
